FARM-GATE.

SPECIFICATION forming part of Letters Patent No. 246,338, dated August30, 1881.

Application filed July 5, 1881.

To all whom it may concern Be it known that I, ABRAHAM L. P11111013, ofAshawa, in the county of Polk and State of Iowa, have invented anImproved Farm- Gate, of which the following is a specification.

The object of my invention is to' provide a gate-operating device thatis simple, cheap, and durable, and that will diminish the power requiredfor operating a gate from a passing vehicle.

Heretofore hand-levers of the first order, a miter-lever, rods, atriangular plate, and a spring-latcl'i have been so arranged andcombined with a swinging gate that it could be operated from a passingvehicle; but as the handlevers have to be mounted upon posts set at adistance from the gate, and being but of the lirst order, makes it hardto operatea gate from a vehicle. To obviate this difficulty I arrangeand combine compound hand-levers, a bellcrank lever, an arm, a spring, asliding latch, conneeting-rods, and a gate as hereinatter fully setforth.

Figure 1 of my accompanying drawings is a top-plan view of my gate andoperating device. Fig. 2 is a perspective view of the same. Togetherthey clearly illustrate the construction and operation 01' my completeinvention.

dis a post set between and in line with posts a c. It has a catch devicefixed upon its side adapted to catch and hold the latch when the gate isopen.

eis a block or arm rigidly fixed upon the 1 top and rear end of the gateZr.

frepresents an arm that projects in an inclined position from the gate.It is rigidly secured to the end of the block 0 and the top board of thegate.

(X0 model.)

g represents a bell-crank lever pivoted to the free and top end of thearm f. It has an extension, 9, that projects outward and downward, andis adapted to prevent the crank-lever gfrom drawing on the latch of thegate as it is closed, and also restricts the movements of thehand-levers, so that they will always be in the right position foroperating the gate.

9 is a metal strip pivoted to the crank-lever g.

h is a sliding latch, that has its bearing formed in or attached to thefront end of the gate.

h is a spring rigidly secured to the lower portion of the gate, andconnected at its top with the rear end of the latch h.

t'is a rod that connects the latch with the crank-lever g.

k k represent hand-levers pivoted on the tops of the posts 0 c.

lrepresents a short rod that connects the strip 9 with the short arm ofthe lever k.

l is a rod that connects the opposite end of the strip 9 with the longarm of the lever 70, near the handle.

' m is a long rod that connects the long arm of the lever 10 with theshort arm of the lever k. (Jonneotingtheleversinthismannermakes each ofthem a lover of the tirst and also of the second order to producecompound levers, by means of which the power required to operate thegate is greatly diminished.-

I claim as my invention- The arrangement and combination of the compoundlevers h /t", the bell-crank lever g, having extension g and pivotedstrip or plate 9, the latch h, the spring h, the rod 'i, and rods l l mwith a gate having a rigid arm,f, substantially as shown and described.
